LIGO Seminar

An important task the remains after the first detection is to improvedetector sensitivity. This requires a deep understanding of thefundamental limits to noise, and possibly a different perspective onwhat it means to be a good detector. The first part of this talk willgo over some of the basic tools used in analyzing quantum limitednoise, and present recent work by Haixing Miao, Yiqiu Ma and theircollaborators on the fundamental quantum limit, or the Quantum CramerRao Bound (q-CRB). The second part of this talk will demonstrate howthis bound can be used to view the optimal detector as an optimalemitter of gravitational waves, and how one can achieve q-CRB bymaximizing amplitude fluctuations of the optical fields inside thecavity.

We plan to broadcast these talks using TeamSpeak. Use a sub-channel of

LIGO Lab called "LIGO Seminar", which is not password protected.
